Passive Skill – Watatsumi Wavewalker

This polearm’s signature passive, Watatsumi Wavewalker, increases the equipping character’s Elemental Burst DMG by 0.12% for every point of the combined Energy Cost of all party members. It can reach up to a 40% boost at Refinement 1 (R1) and up to 80% at Refinement 5 (R5). The bonus scales directly with your team’s total energy needs, making it highly efficient for teams comprised of characters with high burst costs.

How to Obtain Wavebreaker’s Fin

Wavebreaker’s Fin is available exclusively via the weapon event wish banners in Genshin Impact. The polearm is not obtainable through crafting, standard event drops, or the permanent wish pool, so players will need to wait for its rotation on limited weapon banners. Since its debut in version 2.2, it has occasionally reappeared in subsequent weapon banners.
